A large strain multiscale approach using C1 continuity finite element

A second order two scale computational homogenization approach for modeling deformation responses of heterogeneous material at large strain is proposed. The structure at macrolevel is discretized by the C1 continuity displacement based triangular finite elements derived in this contribution, while the standard C0 quadrilateral finite element is used for the discretization at microscale. All algorithms derived have been implemented into the finite element software ABAQUS. The performance of the proposed multiscale approach is demonstrated by an example.
